Well, there could be many reason to visit many great cities in Europe. But for people who don't speak many european languages, for them the priority is to go somewhere they can communicate with locals, ask for great places to eat or to hangout or go partying or sightseeing so for that Amsterdam is your place (everyone speaks english even the old people). But what I recommend is to visit any small shop, get some nice brownies or a bit of small smoking ingriedinets (**sensored) and find the camping spot (its a bit in the outskirts of the city) but amazing place to get high and lay down in the parks to see the sun go down and watch clear sky and just be high as you can manage
